Purpose:

Vector Bit Set

Vector selected bit position set in each element.

Description:

wd[i] = bit_set(ws[i], wt[i])

Set to 1 one bit in each element of v ector ws. The bit position is given by the elements in wt modulo the size of the element in bits. The result is written to vector wd.

The operands and results are values in integer data format df.

Restrictions:

No data-dependent exceptions are possible.

Operation:

BSET_S.B:
   for i in 0 .. WRLEN/8-1
      t = WR[wt]8i+2..8i
      WR[wd]8i+7..8i = WR[ws]8i+7..8i or (07-t || 1 || 0t)
   endfor
BSET_S.H:
   for i in 0 .. WRLEN/16-1
      t = WR[wt]16i+3..16i
      WR[wd]16i+15..16i = WR[ws]16i+15..16i or (015-t || 1 || 0t)
   endfor
BSET_S.W:
   for i in 0 .. WRLEN/32-1
      t = WR[wt]32i+4..32i
      WR[wd]32i+31..32i = WR[ws]32i+31..32i or (031-t || 1 || 0t)
   endfor
BSET_S.D:
   for i in 0 .. WRLEN/64-1
      t = WR[wt]64i+5..64i
      WR[wd]64i+63..64i = WR[ws]64i+63..64i or (063-t || 1 || 0t)
   endfor
